Since I also like war3 game development, I need to “borrow” other people’s art icons in many cases, and the downloaded integrated icons need to be cut out in grid format, so I searched online if there is such a software for custom grid cutting pictures. But it is a pity that the software on the Internet either has unknown functions or does not meet the ideal way of use. At that moment, the seed of “the whole one” germinated in my heart. From the UI layout design of the software to the function production, although the function is single, in the end it ~ “Cutting Monster” was born! ! ! Of course, the icon is also “borrowed”, a software that can cut pictures in a custom grid format, small but powerful! The following is the software download and source code sharing
